Starting and Stopping Methods
Certain Leeson drives (regenerative and non-regenerative)
coast to minimum speed when the inhibit terminals are shorted
to each other. IR COMP and CURRENT LIMIT (FWD TQ and
REV TQ on regnerative drives) are still active while the drive is
in the inhibit mode.
Frequent regenerative deceleration, regenerative braking,
coasting to a stop, or decelerating to minimum speed produces
high torque. This may cause damage to motors, especially
gearmotors that are not properly sized for the application.
Warning
For frequent starts and stops, use regenerative
deceleration (shorting RB1 and RB2), regenerative
breaking (shorting INHIBIT terminals to each other),
coasting to a stop (shorting INHIBIT-RUN terminals 1 and
2), or decelerating to minimum speed (shorting S2 to S0).
Do not use any of these methods for emergency stopping.
They may not stop a drive that is malfunctioning.
Removing AC line power (both L1 and L2) is the only
acceptable method for emergency stopping.
